Write a subroutine that will receive a char input value. This subroutine should then use a switch statement to determine if the char is a vowel, consonant, digit, or other type of character.

Write the subroutine only,
This is in C++

##### Expert Solution

The C++ code to find the given character is vowel or consonant or special character or a number is:

#include<iostream>
#include<cstring>
using namespace std;

//Determine() function checks if the char ch is
// a vowel or consonant or number or special character
// This function returns nothing
void Determine(char ch){
//Checking if the char is a number using ascii values
//ch-0 gives ascii value of character in ch
//Ascii values of digits are 48 to 57
if(ch-0>=48 && ch-0<=57){
ch=1;
}
//If ch is not a number or alphabet, then any other ascii value
//is a special character
if((ch-0<=48 || ch-0>=57) && (ch-0<=97 || ch-0>=122) && (ch-0<=65 || ch-0>=90)){
ch=2;
}
//Using switch case to determine and print appropriate result
switch (ch)
{
//for case a e i o u printing vowels.
case 'a':
case 'e':
case 'i':
case 'o':
case 'u':
cout<<"Entered character is a vowel"<<endl;
break;
//We checked for digits using ascii values and
//assigned ch=1 if ch is a digit
//so for case 1 we need to print its a number
case 1:
cout<<"Entered character is a number"<<endl;
break;
case 2:
cout<<"Entered character is a special character"<<endl;
break;
default:
cout<<"Entered character is a Consonant"<<endl;
break;
}
}

int main(){
//Declaring a variable of type char
//char variables can store only one character
char ch;
//Promprint for input and reading a character
//Remember, if you enter a word instead of char
//Compiler wont throw a error, instead it stores first char of word
cout<<"Enter a character: ";
cin>>ch;
//Calling Determine() function to determine
//if ch is vowel or consonant or other
Determine(ch);
}

I have used ascii values to check for numbers and speacial characters. Then using a switch case first I checked for a,e,i,o,u cases and printed vowel if true, if false based on previous checks I wrote cases to print if it is a number or special character.

I have provided comments in the program explaining the process and the functions used. I have tested the code for all possible cases and validated the outputs.

I am sharing few output screenshots for your reference.

Let us see what will be the output if we try to enter a word as input:

As you can see, the compiler didn't throw any exception, instead it took the first letter of the word and stored in ch. So we got output as consonant.

Thank you.
